Abstract

Improvements in the construction of servomotors for pressurized fluids, of the type comprising a housing, internally divided into two front and rear parts by a fixed separation, two mobile walls slidably arranged on each side of said separation and each of the walls dividing one of said housing parts, in two chambers namely an anterior reference pressure and a rear control one, the walls are rigidly interconnected by a hollow core prolonged by sliding and in closing conditions, through aligned openings in said separation and in the end walls of said casing; a valve actuated by the operator, located inside the core and which controls the difference of pressures through said movable walls, and a force transmission rod functionally connected to the core by means of a reaction transmission device, characterized in that the valve includes two independent valve devices placed in separate cavities of the core, each controlling the pressure difference through one of the moving walls, and driven respectively by aligned valve pushes, the first of them directly driven by the operator and adapted to form a stop, in the forward movement, the second arranged to receive a reaction force of the force transmission rod through the reaction transmission device.
